KNOCKDOWN SEAT.

Specification of Letters Patent;

Patented Sept. 20, 1910.

To all whom it may concern:

Be it known that we, WILLIAM A. KIRK- PATRICK and Joint E. ROBBINS,citizens of the United States, residing at Greensburg, in the county ofDecatur and State of Indiana, and CLIFFORD P. KIRKPATRICK, a citizen ofthe United States residing at Indianapolis, in the county of Marion andState 0 Indiana, have invented certain new and useful Improvements inKnockdown Seats, of which the following is a specification.

The object of our present invention is to provide a strong and usefulseat which may be readily assembled and disassembled, for storage,shipment and the like; or, in other words, quickly and easilytransformed from the assembled to the knocked-down condition or viceversa. Said invention will be first fully described, and the novelfeatures thereof pointed out in the claims.

Referring to the accompanying drawings, which are made a part hereof,and on which similar reference characters indicate similar parts, Figure1 is a perspective view of a piano bench embodyin our present invention;Fig. 2 a central Ion itudinal vertical section of the view thereof; Fig.3 a detail sectional view at the point where the top and the u per endof one of the legs are joined, and Fig. 4 a detail sectional viewillustrating the means of connecting the stay bar and the cross bars bywhich the pairs of legs are united.

While we have illustrated (and shall describe) this invention as appliedto a piano as will be readily understood, be used in various kinds ofother seats and structures without departing from my invention. In thisstructure a top 21 has shallow recesses formed in its under side atpoints where the upper ends of the legs approach it, and a portion ofeach of said recesses is occupied by a metal keeper plate 22 having anundercut edge facing the remainder of such recess, all as best shown inFig. 3. Said plate may be secured in any desired manner, as by screws23. Each of the legs 24 has secured to its upper end a correspondingplate 25, the projecting toe of which is adapted to pass below theoverhangin edge of plate 22. These legs are inserte by being first lacedin the position indicated by the dotte lines in Fig. 2, and

then swung down to approximately the positlon they occupy when thestructure is finished, as shown by the full lines in said figure, afterwhich they are drawn tightly together by the stay bar which has rightand left hand threaded bolts secured in its ends.

In the construction shown, the legs 24 are formed in pairs, which areconnected by cross bars 28, and these cross bars are provided withthreaded plates or nuts 26, as is most plainly shown in Fig. 4. The staybar 27 has in its ends the right and left hand threaded bolts or boltportions 29 and 30, and these are adapted to enter the plates or nuts26. On account of the right and left hand formation of the threads, arevolving of this stay bar will draw the cross bars 28 tightly againstthe ends thereof, and at the same time bring the legs 24 to their finalor operative position, as shown in the drawings. All that is necessaryin order to disassemble this structure is to revolve the stay bar in theopposite direction until the bolts and nuts separate, when the legs canbe detached from the body by merely swinging them out to the positionindicated by the dotted lines in Fig. 2.

Having thus fully described my said invention what.I claim as new, anddesire to secure by Letters Patent, is,

1. A knock-down cabinet structure comprising a connecting member, a pairof legs, and a second connecting member connected to the legs by a pairof oppositely threaded screws, the connection between each leg and thefirst connecting member comprising two plain plates of substantially thesame thickness having their adjacent edges oppositely and matinglybeveled, one of said plates being secured to the upper end of the legstructure and the other of the said plates being secured 'to the firstmentioned connecting member and lying within a socket formed in saidfirst mentioned connecting member and having one dimension substantiallyequal to the combined dimensions of the two plates when their bevelededges are mated together, substantially as and for the purpose setforth.

2. In a knock-down cabinet structure, the combination of a pair ofseparable members one carrying a plain thin plate 25 having a bevelededge, and the other carrying a plain thin plate 22 having a beveled edgemata-ble diana, this ninth dayof August, A. D. one 1c With the bevelededge (if the plate 25), said thousand nine hundred and. nine. lastmentioned late 22 ein 'inounte Wit I in a socket fOIl 1 16Cl in the niember to Which WILLIAM KIRKPATRICK it is attached and said socket havinga di- ROBBINS niension substantially equal to the dimen- OLHFORDKIRKPATRICK sion of the tWo plates When mated together. lVitnesses:
